摘  要:利用河北省1970-2019年96个地面气象观测站逐日平均气温观测数据,采用气候趋势倾向法,参照采暖供热相关规范,分析河北省采暖期气温变化特征、采暖期长度及采暖强度变化特征。结果表明:近50 a河北省采暖期平均气温呈上升趋势,采暖期度日呈下降趋势,近50年平均气温趋势倾向值为0.219℃/10 a。采暖初终日和采暖期长度均存在年际变化振荡,但总体呈现出采暖初日推后、终日提前、采暖期长度缩短的趋势。Based on the daily average temperature observation data of 96 surface meteorological stations in Hebei Province from 1970 to 2019,the characteristics of temperature change,heating period length and heating intensity in heating period of Hebei Province were analyzed by using the climate trend method and referring to the relevant heating standards.The results show that:in recent 50 years,the average temperature in heating period of Hebei Province shows an upward trend,while the degree day in heating period shows a downward trend,and the trend value of average temperature in recent 50 years is 0.219℃/10 a.Both the beginning and end days of heating and the length of heating period have interannual oscillation,but the overall trend is that the beginning and end days of heating are postponed,the end days are advanced,and the length of heating period is shortened.
